This timer is specificaly made to make using the Pomodoro Technique easy. The Pomodoro Technique is a productivity technique invented in the early 1990s by Frencesco Cirillo. The Pomodoro Technique focuses on breaking down tasks into short time intervals.

The user works for 25 minutes, this is then followed by a 5 minute break. This cycle repeats itself until the task is done.
